I dislike the current emphasis on hard seats (and this applies to most other brands as well- Toyotas and Hondas are the worst). Enthusiast magazines can rave all they want about great support, etc, but the softer seats in friend's '92 Caravan are more comfortable than these in my 2013.
I have an SXT model, which is sort of mid level in Grand Caravans, and it does have a power seat. However, that is an OPTION, and it should be standard above the SE model.

I find the front seat contours to my back giving me plenty of lower back support which is one of the major reasons I originally purchased this vehicle.
